TIRE PRESSURE WARNING SYSTEM, Diagnostic DTC:C2198/98

DTC Code DTC Name
C2198/98 Initialization Switch (for Test Mode DTC)

DESCRIPTION

The switch circuit inside the combination meter assembly turns on and off according to the steering pad switch assembly operation.

During test mode, when the steering pad switch assembly is operated, "TPMS" is selected on the multi-information display and the "ENTER" switch (steering pad switch assembly) is pressed, the tire pressure warning light illuminates, and when the "ENTER" switch (steering pad switch assembly) is not pressed, the tire pressure warning light blinks at 0.125 second intervals.

DTC No. DTC Detection Condition Trouble Area
C2198/98 Test mode procedure is performed.

  • Steering pad switch assembly

  • Spiral with sensor cable sub-assembly

  • Wire harness or connector

  • Tire pressure warning ECU and receiver

CAUTION / NOTICE / HINT

Note


  • When replacing the tire pressure warning ECU and receiver, read the transmitter IDs stored in the old ECU using the GTS and write them down before removal.

  • It is necessary to perform initialization (See page ) after registration Click here of the transmitter IDs into the tire pressure warning ECU and receiver if the ECU has been replaced.
